Title: X-ray imaging apparatus
Inventor: YANOME MASAKATSU
IPC: A61B6/04
Filed: 1990-01-26
Abstract: PURPOSE:To make a response speed rapid, to enhance stop accuracy and to reduce the load of an operator by mounting the balance means of a handle and preventing that a detection means detecting the movement of the handle is erroneously operated by one component of the wt. of the handle. CONSTITUTION:The handle 20 of a power assist mechanism has a pair of slide parts 20-1 sliding with respect to the housing 3-1 of a spot apparatus and wires 31 are extended from a pair of the slide parts 20-1 and guided by a plurality of pulleys 32 to be connected to a counterweight 30. When the wt. of the handle 20 is set to W1 and that of the counterweight 30 is set to W2, both wts. are set to W1 W2. Therefore, the handle 20 is in a weightless state and it is prevented that a pressure sensor 21 is erroneously operated by the own wt. of the handle 20 as is conventional. As a result, the width of the non-sensitive band of the pressure sensor 21 can be narrowed and a response speed is increased and stop accuracy can be enhanced.

Title: Optical connector
Inventor: SHIINO MASAHITO
IPC: G02B6/36
Filed: 1999-01-26
Abstract: PROBLEM TO BE SOLVED: To decrease the time for connection without decreasing reliability by coating an optical fiber fixed with an adhesive with a protecting agent injected through a window. SOLUTION: An optical fiber 4a of an optical fiber 4 inserted through a rubber boot 8 and peeled off its coating is inserted into a hole 5 and fixed. The optical fiber 4a is fixed by, first, a small amt. of an adhesive A (such as a cyanoacrylate instant adhesive), which is dripped through a window 9 to a ferrule 7. After the adhesive A is cured, an adhesive B (such as a two-liquid epoxy adhesive) as a protecting agent is dripped through the window 9 to reinforce the fixed state and to protect the optical fiber 4a. By using two kinds of adhesive A and adhesive B together, the injection time of the adhesive increases compared to a process using one kind of adhesive, however, the amt. of the adhesive A is small and it can be cured in a short time, which decreases the time till the connector can be used.

Title: Development method under adjustment of image density
Inventor: ANZAI MASAYASU
IPC: G03G15/06
Filed: 1980-02-18
Abstract: PURPOSE:To obtain a superior image free from any photographic fog despite high- speed development by selecting and adjusting the image density by changing the bias voltage of the 1st developing roll and keeping the voltage upon the 2nd developing roll constant thereby performing development at the time of developing an electrical latent image with a toner. CONSTITUTION:Arrangement is so made that, at the multiroll developing during high-speed development, the bias voltage of the 1st developing rolls 51 are made selectable in three steps, A, B, C, with a switch 9 for the latent images 3 of the recording layer 2 on a photoreceptor substrate 1, whereby the image density and tone of the reproduced images is changed according to the densities of the original images. If this is so controlled as to allow the sufficient toner to be picked up on the latent images 3, the toner also adheres to the areas where there is no charge, and this produces a photographic fog. This is passed to the 2nd developing roll 52 to remove the toner picked up on the areas where there is no charge, whereby the toner images 4 free from photographic fogs 2 are obtained. The 2nd developing roll 52 is kept at approximately the same constant voltage as the latent image voltage including 0V. In this way, the print of a desired density is obtained.
